Thyroid nodules are a common general surgical disease and are common in young women, and traditional surgery for open thyroidectomy has been performed for over 100 years and is a safe and well-established surgical procedure for treating thyroid disease. However, the high-incidence population of thyroid nodules is female, the traditional operation mode causes about 6cm-8cm operation scars on the neck of a patient, and neck discomfort and paresthesia occur after the operation, which undoubtedly brings huge psychological burden to the patient.

Endoscopic techniques have been used for surgical treatment of thyroid disorders in almost two decades since the first endoscopic parathyroidectomy performed by Gagner et al in 1996. In 2012, my wang stock river carries out the first instance of carrying out the operation of oral cavity vestibular thyroid to bring the endoscopic thyroid surgery into the completely scar-free era of natural orifice (N0 TES), oral cavity vestibular thyroid surgery is carried out in the medial labial mucosa area of lower lip, completely oral cavity vestibular endoscopic thyroidectomy is compared with other incomplete oral cavity vestibular endoscopic thyroidectomy, not only has the general advantage of endoscopic thyroid surgery, but also accomplishes: (1) the oral cavity incision is covered by oral mucosa, and the healing is rapid after the operation, and no scar is left on the body surface; (2) the visual angle is from the head side to the foot side, so that the lymph nodes in the central area can be cleaned conveniently; (3) the operation trauma is small. However, due to the particularity of the oral microbial environment, the operation type changes the one-class incision of the traditional thyroid operation into the two-class incision, while dentition, jaw, lip and buccal mucosa are in an open state, and saliva generated in the oral cavity easily passes through teeth, gum, lip and buccal mucosa to cause postoperative effusion and wound infection to the operation area on the inner side of the lower lip; meanwhile, due to the special structure of oral bacteria and the loose structure of the neck, once soft tissue infection occurs in an operation area, wide cellulitis is easy to form, the consequence is serious, even the life is threatened, and the development of the operation is severely limited.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4, the present embodiment provides an oral cavity isolating device, which includes a vestibular septum 1 and a lip expanding plate 2; the vestibular baffle plate 1 is matched with the dentition of a human body, and the connecting end of the lip expansion plate 2 is connected with the vestibular baffle plate 1; the lip expanding plate 2 is arranged in an arch shape along the length direction, and the lip expanding plate 2 is matched with the inner side of the lip of the human body; when the vestibule-expanding device is used, the lip expanding plate 2 corresponds to the vestibule partition plate 1 in the front-back position, so that the dentition of a human body is positioned behind the vestibule partition plate 1, the lip expanding plate 2 is positioned on the inner side of the lips, and the lip expanding plate 2 is contacted with the lips and buccal mucosa of the human body, so that the lips of the human body are expanded by the lip expanding plate 2 to be in an arch shape consistent with the lip expanding plate 2; the lip expansion plate 2, the vestibular clapboard 1 and the lower lip form an independent vestibular space. An illustration of a use of an oral isolation device is shown in fig. 2.

In order to avoid the scratching of the inner wall of the oral cavity of the human body caused by the edges and corners at the two ends of the vestibule baffle plate 1, the two ends of the vestibule baffle plate 1 are both arc-shaped or arc-shaped, and the experience of patients is improved. Moreover, the vestibular baffle plate 1 is in a convex arc shape, the shape of the vestibular baffle plate 1 is designed to be just corresponding to the shape of the dentition of the human body, so that the vestibular baffle plate 1 can be effectively contacted with the dentition when a patient performs an operation. As another embodiment, the vestibular partition plate 1 is arc-shaped, the upper end of the lip expansion plate 2 is also arc-shaped, and the upper end of the arc-shaped lip expansion plate 2 is coaxial with the arc-shaped coaxial central line of the vestibular partition plate 1; the arc shape design of the upper ends of the vestibule clapboard 1 and the lip expanding plate 2 is more matched with the corresponding nesting position in the oral cavity of the human body, thereby improving the comfort of the patient when in use.

In addition, the upper end of the lip expanding plate 2 is provided with an outward flange 21, so that the inner side of the lip is better matched with the lip expanding plate 2, and the stability of self-anchoring formed between the lip expanding plate 2 and the lip is improved. The upper end of the lip expanding plate 2 is in arc surface transition with the connection part of the turned-over edge 21, so that the phenomenon of corner angle at the connection part of the lip expanding plate 2 and the turned-over edge 21 is eliminated, and the comfort of the patient when the inner lip wall of the lip is contacted with the lip expanding plate 2 is improved. Meanwhile, the cross section of the lip expanding plate 2, close to the contact end face of the upper lip, in the length direction of the lip expanding plate 2 is concave, when the lip is in contact with the lip expanding plate 2, the lip automatically slides into the concave part of the lip expanding plate 2, the relative position of the lip expanding plate 2 in the oral cavity is conveniently adjusted automatically through the lip, and meanwhile, the self-anchoring effect between the lip and the lip expanding plate 2 is conveniently realized.

Specifically, the distance between the two arched ends of the lip expanding plate 2 is marked as d, and d is 50mm-80 mm; the width of the lip expanding plate 2 is recorded as b, b is 30mm-50mm, the height of the lip expanding plate 2 is recorded as h, and h is 15mm-30 mm. The length of the vestibular baffle plate 1 is 60mm-100mm, and the width of the vestibular baffle plate 1 is 30mm-60 mm. The size design of the vestibular clapboard 1 and the lip expanding plate 2 ensures that the vestibular clapboard 1 and the lip expanding plate 2 are more suitable to be matched with the oral vestibule of the human body.

In conclusion, according to the theoretical basis of the potential gap between the labial mucosa of the oral vestibule and the dentition, the vestibule baffle plate 1 is arranged in front of the dentition, the lip expanding plate 2 is sleeved on the inner side of the labial mucosa of the oral vestibule, so that the lip expanding plate 2, the vestibule baffle plate and the lower lip form an independent vestibule space, namely, the vestibule baffle plate 1 and the lip expanding plate 2 artificially construct a physical barrier in the oral vestibule, the physical barrier can effectively isolate the contaminated areas of the dentition, the upper lip and the buccal mucosa, and the operative area on the inner side of the lower lip forms an independent space, thereby avoiding the contact between the operative area and the contaminated area, and greatly reducing the chances of infection of postoperative effusion and soft tissues of the operative area; meanwhile, the lip expanding plate 2 is designed in an arched shape, so that the shape of the lip expanding plate 2 is consistent with the outline shape of the lip when the lip is opened, and when the lip expanding plate 2 is arranged on the inner side of the lip, self-anchoring is formed between the lip expanding plate 2 and the lip, so that the vestibule diaphragm 1 and the lip expanding plate 2 are stably fixed in the oral vestibule, and the situation that an operation area is polluted by bacteria due to the displacement of the vestibule diaphragm 1 caused by operation in an operation is avoided; meanwhile, due to the flanging design of the lip expanding plate 2, the inner sides of the lip and the cheek are better matched with the lip expanding plate 2, and the self-anchoring stability formed between the lip expanding plate 2 and the upper lip is improved.

It is worth noting that the oral cavity (oral cavity) is the initial part of the digestive tract, which communicates with the outside through the cleft mouth and then continues with the pharynx through the isthmus. The oral cavity is provided with organs such as teeth, tongue and the like, the front wall of the oral cavity is a lip, the side wall of the oral cavity is a cheek, the top of the oral cavity is a palate, and the bottom of the oral cavity is a mucous membrane, a muscle and other structures. The oral cavity is divided into an oral vestibule (oral cavity) in the antero-lateral part and an oral cavity (oral cavity) in the postero-medial part by means of upper and lower dental arches. The buccal cavity is located between the lips and cheeks and the dentition and gum. When the upper and lower dentitions are occluded and the lips are closed, the vestibule of the oral cavity is in a horseshoe-shaped potential cavity and is communicated with the inherent oral cavity through a gap between the last molar and the mandibular ascending branch.

The oral cavity isolating device is a surgical instrument developed according to the theoretical basis of potential gaps between oral vestibule lip mucosa and dentition and the clinical experience of a conventional surgical disinfection drape, solves the clinical problem of intercommunication between the oral vestibule and the inherent oral cavity in an operation, enables the rear boundary of an oral vestibule operation area to be changed into a base formed by a vestibule clapboard 1 from the inherent oral cavity (dentition, jaw, pharynx and other structures), further limits the operation area to a lip mucosa area with the length of about 6cm of the lower lip through a lip expanding plate 2, effectively physically isolates the oral vestibule from the inherent oral cavity, thereby artificially constructing the oral vestibule into an independent space, avoiding the contact between the operation area and a polluted area, and converting the oral vestibule operation from a two-type incision into a one-type incision operation. In medicine, one type of incision refers to a clean incision, one that does not enter the inflammatory zone, one that does not enter the respiratory, digestive, and genitourinary tracts, and one that does meet the above criteria for closed wound surgery; type two incisions refer to clean-contaminated incisions that are surgically introduced into the respiratory, digestive, or genitourinary tract without significant contamination, such as non-infectious and successfully completed biliary, gastrointestinal, vaginal, and oropharyngeal surgeries; the three types of incisions refer to contaminated incisions, fresh open wound surgeries, surgeries entering acute inflammation but not suppurative areas, gastrointestinal contents obviously overflow and contaminated, and patients with obvious defects in aseptic technique in the surgeries; four types of incisions refer to filth-infected incisions, old wound surgery with inactivated tissues, and clinical infection or organ perforation surgery. The incidence of infection was statistically found to be 1% in clean incisions. Therefore, the application of the vestibular diaphragm 1 and the lip expansion plate 2 in the oral vestibular endoscopic thyroidectomy brings great benefits to patients.

The surgical incision of the oral cavity vestibule-thyroid surgery is concentrated on the lower vestibular sulcus and the lower labial mucosa, the oral cavity vestibule is separated from the inherent oral cavity by the vestibular clapboard 1 and the lip expanding plate 2, so that repeated contact between surgical instruments and dentition and mucosal tissues in the inherent oral cavity in the surgery is avoided, the chance that oral bacteria enter the neck surgical cavity through the migration of the surgical instruments is greatly reduced, the postoperative soft tissue infection of the neck is effectively avoided, the surgical complications are reduced, and meanwhile, the hospitalization time and the diagnosis and treatment cost of a patient are also reduced; meanwhile, the successful application of the vestibular diaphragm 1 and the lip-expanding plate 2 ensures that the oral vestibular thyroid surgery (NOTE) breaks through the original limitation that may cause infection, thus the oral vestibular thyroid surgery really becomes a safe, effective and completely scar-free surgery and can be applied to more patients.

In addition, aiming at the oral cavity disinfection technology, the oral cavity is operated as a whole for oral postoperative disinfection in both stomatology and maxillofacial surgery at home and abroad, and the surgical area disinfection is carried out by adopting a method of disinfecting and soaking by adopting 1% povidone iodine solution and 0.25% chlorhexidine water solution. Meanwhile, the bacterial count of different parts in the oral cavity is remarkably different, and the bacterial count of periodontal and dental plaque can be hundreds of times higher than that of mucosal tissue. However, the vestibule diaphragm 1 and the lip-expanding plate 2 are applied to the oral vestibule operation, so that the oral vestibule and the inherent oral cavity can be conveniently separated in the operation, the operation area can be disinfected, the whole oral cavity is prevented from being used as a postoperative disinfection object, and the dentition containing a large amount of bacteria outside the area is prevented from being disinfected, so that the condition that the postoperative oral cavity is infected in a large amount is avoided, and postoperative complications and operation risks are greatly reduced.
